Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a blood collection placement rack. Background Art

[0002] Vascular surgery is a branch discipline of surgery, mainly for the prevention, diagnosis and treatment of peripheral vascular diseases except cerebrovascular and cardiovascular diseases; during the treatment process, blood collection tubes are required, and a placement rack is needed for storing them.

[0003] It is known that Chinese Patent CN213913910U discloses a blood collection tube placement rack for vascular surgery, including a buffer seat. The top end of the buffer seat is movably connected with a bottom plate. The top end of the bottom plate is fixed with symmetrically arranged columns in pairs. The top end of the column has a placement plate. A rotating shaft is rotatably penetrated through the outer wall of one side of the placement plate. The rotating shaft extends into the cavity of the placement plate and is rotatably sleeved with a first bevel gear at the end. Both sides of the first bevel gear are meshed with a second bevel gear. A lead screw penetrates through the inner wall of the second bevel gear. The lead screw is connected to the placement plate by a bearing. A ball nut is rotatably sleeved on the outer wall of the lead screw. The top end of the ball nut is fixed with a sliding block; a sliding groove for the sliding block to slide is opened at the top end of the placement plate. The sliding block extends to the outer wall of the sliding groove and is fixed with a clamping plate at the end. An equidistantly distributed protective pad is fixed on one side surface of the clamping plate; through the provided clamping plate, the blood collection tubes on the placement plate can be clamped and fixed conveniently and quickly, ensuring the placement function of the placement plate for the blood collection tubes.

[0004] However, it is found that the above-mentioned solution has the following problems in the implementation of related technologies: uneven cell stratification. During the static process, different components in the blood may stratify, and it will also cause the blood not to be fully mixed with the anticoagulant, easily resulting in blood coagulation, which will interfere with subsequent operations or detections. Secondly, in the prior art, the stability effect is poor. During the operation process, the placement rack is prone to displacement or tipping due to slight external collisions or vibrations, resulting in sample contamination or damage. Summary of the Invention

[0039] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention.

[0040] Embodiment 1

[0041] Please refer to Figure 1 - Figure 8 , a blood collection placement rack, including a support 1 and a test tube rack 2. An inner side of the test tube rack 2 is provided with a mounting plate 3, and the mounting plate 3 is fixedly installed on a plug-in board of the test tube rack 2. A plurality of columns of fixing components 4 are sequentially arranged at the bottom of the mounting plate 3 from left to right;

[0042] Both sides of the inner wall of the support 1 are fixedly installed with fixing frames 5. Inverted L brackets 6 are fixedly installed on both side walls of the test tube rack 2, and the inverted L brackets 6 are inserted into the fixing frames 5;

[0043] Two racks 7 are symmetrically and fixedly installed at the bottom of the test tube rack 2. Two rotating rods 9 are rotatably installed on the inner bottom wall of the support 1. Plate gears 10 are fixedly installed at the tops of the two rotating rods 9, and the plate gears 10 are meshed with the racks 7;

[0044] A driving component 8 is arranged at the bottom of the support 1, and the driving component 8 is connected to the rotating rod 9;

[0045] Two positioning components 11 are arranged through the support 1, and the bottom of the positioning component 11 is adsorbed to the workbench.

[0046] A blood collection placement rack provided by the present invention, when in use, enables the support 1 to firmly adsorb on the workbench through the positioning component 11. After that, when an artificial inserts a test tube into the test tube rack 2, through the fixing component 4 on the mounting plate 3, the test tube inserted on the test tube rack 2 can be quickly and tightly clamped. Then, the driving component 8 drives the two rotating rods 9 on the support 1 to rotate. Then, the rotating rotating rods 9 synchronously drive the two plate gears 10 thereon. When the left plate gear 10 meshes with the rack 7, with the cooperation of the fixed frame 5 and the inverted L-shaped frame 6, the test tube rack 2 can be stably driven to move backward. Then, when the left plate gear 10 moves away from the rack 7, the right plate gear 10 will mesh with another rack 7, so as to drive the test tube rack 2 to move forward, and further enable the test tube rack 2 to shake back and forth, which can ensure that the blood sample is fully mixed with the anticoagulant or other additives, and prevent component stratification or coagulation.

[0047] Further, the fixing component 4 includes a fixed sleeve 41 fixedly installed at the bottom of the mounting plate 3. Two clamping frames 42 are symmetrically pin-connected to the fixed sleeve 41. A spring 43 is fixedly installed on one side of each of the two clamping frames 42, and the other end of the spring 43 is fixed to the fixed sleeve 41.

[0048] Specifically, when the test tube is inserted into the test tube rack 2, the clamping frames 42 pin-connected to the fixed sleeve 41 can quickly and tightly clamp the test tube inserted on the test tube rack 2 under the action of the spring 43, thereby avoiding the collision phenomenon between the test tube and the test tube rack 2 due to the gap left when the test tube rack 2 shakes. At the same time, it also enables the test tube to be clamped and fixed without manual intervention.

[0049] Further, a protective pad 16 is fixedly installed on one side of the clamping frame 42, and the material of the protective pad 16 is rubber.

[0050] Specifically, through the protective pad 16, the friction between the clamping frame 42 and the test tube can be increased, and at the same time, the test tube can be protected to avoid scratching the surface of the test tube when the clamping frame 42 clamps.

[0051] Further, the driving component 8 includes a motor 81 fixedly installed at the bottom of the support 1. The output end of the motor 81 penetrates through one side wall of the support 1 and is fixedly installed with a driving gear 82. Driving gears 83 are fixedly installed on the outer side walls of the two rotating rods 9, and the two driving gears 83 are both meshed and connected with the driving gear 82.

[0052] Specifically, the driving gear 82 is driven to rotate by the motor 81, and then the rotating driving gear 82 drives the driven gear 83 meshed with it, so that the rotating rod 9 and the plate gear 10 can rotate, and further, the test tube rack 2 can swing back and forth under the cooperation of the plate gear 10 and the rack 7.

[0053] Further, the positioning component 11 includes a threaded rod 1101 penetrating through the bracket 1. The threaded rod 1101 is rotatably connected to the bracket 1. A fixing column 1102 is threadedly connected to the outer side wall of the threaded rod 1101, and a pair of suction cups 1103 are fixedly installed at the bottom of the fixing column 1102.

[0054] Specifically, by manually rotating the threaded rod 1101, under the limiting cooperation of the bracket 1, the fixing column 1102 can drive the suction cup 1103 to descend, and further, under the action of the suction cup 1103, the bracket 1 can be firmly adsorbed on the workbench, avoiding the test tube rack 2 from swinging back and forth, or the bracket 1 and the test tube rack 2 from shifting and toppling due to external collision or vibration.

[0055] Further, an anti-collision pad 17 is arranged in the insertion hole on the test tube rack 2, and the anti-collision pad 17 is fixedly installed on the test tube rack 2. The anti-collision pad 17 is made of rubber.

[0056] Specifically, the anti-collision pad 17 is beneficial to improving the protection effect of the test tube.

[0057] Embodiment 2

[0058] Based on Embodiment 1, in this embodiment: strip-shaped grooves are formed on both of the inverted L-shaped frames 6, and a plurality of rollers 18 are arranged inside the strip-shaped grooves, and the rollers 18 are rotatably installed on the inverted L-shaped frames 6.

[0059] The technical solution provided in this embodiment is that through the rollers 18, the friction between the fixed frame 5 and the inverted L-shaped frame 6 can be reduced, and further, the test tube rack 2 can move back and forth easily.

[0060] Embodiment 3

[0061] Based on Embodiment 1, in this embodiment: an installation groove 12 is formed on the inner bottom wall of the test tube rack 2. A rubber pad 13 is arranged inside the installation groove 12. A rectangular frame 14 is sleeved outside the rubber pad 13, and the rubber pad 13 is fixedly installed on the rectangular frame 14. Hand-tightening screws 15 are threadedly connected to both sides of the bracket 1, and the screw end of the hand-tightening screw 15 abuts against the rectangular frame 14.

[0062] The technical solution provided by this embodiment is as follows: Manually rotate the hand-tightening screw 15 so that its screw rod end tightly abuts against the rectangular frame 14, so that the rubber pad 13 can be stably fixed in the installation groove 12 on the test tube rack 2. Furthermore, under the action of the rubber pad 13, the test tube inserted into the test tube rack 2 can be buffered and shock-absorbed to prevent the bottom of the test tube from being damaged due to hard contact with the test tube rack 2 when the test tube is inserted into the test tube rack 2. On the contrary, when the hand-tightening screw 15 is manually reversed, the rubber pad 13 can be easily replaced.

[0063] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
